* Use a slightly better (but still not exact) approximation for the view vector when pre-shading the light cache. This still doesn't give exactly the same results as non-light-cache shading, but it's better. Will investigate getting a better view vector when there's more time - or if anyone has a simple formula to derive shi->view from shi->co that would be great to hear about too :)
